JG TOUCHPAD
When using Zones 7 or 8 for
controlling radiator circuits
instead of UFH, the switch on the zone
must be in the OFF position to prevent
the UFH pump from operating
This will result in fewer zones being
available for UFH.
The Zone Valve is activated by connecting
the demand wire (normally brown) to the
positive terminal of the appropriate actuator
connection as shown.
Notes

See Note 1
See Note 2
Up to 2 Actuators can be connected to the
same terminal. ie max 6 actuators per
zone block.

Optional UFH Manifold Zone Valve
used only to prevent flow of water
to manifold when UFH is off and another

If Zone Valve is not used a link needs to
be placed between motorised valve
connections marked 1 & L to enable
boiler firing,

When more than one JGUFH1 is used
in an installation the boiler enable terminal
must be connected to the boiler from each
individual wiring centre.
